Toall whom ify may concern Be it known that I,`JoHN DALnY, a sub.

ject of the King of Great Britain, residing atA Pawtucket, in the count and State of Rhode' Islan have invented of Providence' certain new and useful Improvements in- WVarp-Winding Devices, of.

In lace machines the 'rolls for carrying i the warp strandsare much longer. than those 2o ing in series end'to end a number of windingt for looms, andthe .devices employed for winding loom beams are inadequate me# chanically and leconomically when attempted to be employed Vin winding lace warp rolls.` ted to' wind the strands upon lace or jack in front of-each mill, an operator for each millfmanually reciprocated. a.

Inits present and preferred embodiment a pluralityvof creels or ]acks 15 radially arranged side by side, the number of jacks being determined by the length of the warp beam intended to be Wound. Each jack comprises a single vertical frame cons1sting`of end posts 16, standards or bases 17 vand cross Adjacent Athe spindles are oneof the posts-16 are pivotally mounted series of horizontally disposed laterally prothe apexY of eachfcross of each al'm --is fixed a series of wire guide eyes 34.

The preferred Iform mechanism for adapted for carrying the operating parts, 'such as end uprights 43 havlng spacedy upwardly directed arms 44, midway between adapted to yreceive the shaft 47 of a tension tion consists in suchparts and combinations of parts as fall within the scope of the appended claim.-

In the accompanying 'a part of this specification,

shown merely a preferred ment of my invention,

and 'in which is form of embodidrawings which are 52." Resting in slots 53 roll 48. Integral with the -upperportions of the uprights are rearwardly directed brackets 49 one-of which is provided with a slot l50 to receive the shaft 51 ofthe warp rolll 105 in the tops of thev arms 44 are the 'shafts 55 of idler rolls 56. As shownin Fig. 6 the roll 48 has a fabric covering 58, and the rolls 56 have a similar covering 59. The driving means includes a ;I l

main shaft 61 journaled in the uprights carrying driving pulleys 62, a wheel 63, and

' momentum wheel 64. A second shaft 65 in the uprights carries a gear 66 and wheel 67 driven by a belt 68 on the wheel 63. The gear 66 meshes with a gear 70 fast on a lshaft 71v mounted in a bearing 73 on' the bracket and having a couplin 74 detachably engaging the warp roll sha t 51. By the described or other. convenient mechanism the warp roll is rotated.

For temporar1ly elevating the idler warp roll 58 from` its seat the followingl mechanism is employed. The ends of the shaft 47 in the front and rear of the frame are the are loose in the ends of arms-7 5 fixed to shaft 76 journaled in sleeves 77 on a bracket 78 on the front ofthe uprights. Fast to the shaft is an arm 79 pivoted toy one end of a connecting rod 81 whose other end is pivv 20 oted to the upper end of a lever 83 mounted intermediate its length upon a pin 84 in a standard 85 whose base 86 is Xed to the oor. Upon the base is pivoted a latch 87 pressed by a springv 88 and located in the path of a pedal 90 provided with a bevel 91 to assist en gement with the latch when the lever is epressed.

Fast to the uprights outside the rolls 56 longitudinal ba s 93 and 94 respectively,

. formed of angle iron. Removably attached by screws 97 to the face of the upright portion of the bar 93 are a series of brasses, thread plates, or reeds 98 arranged edge to edge in each plate, as shown in Fig. 5. Each plate has four horizontal rows of five perforations 99, and below said rows are parallel rows of four perforations 100 in staggered or inclined relation to the yxerforations of the first mentioned rows.

he number of perforations in each row corresponds with the numbers of guide eyev lets 34 and 37 respectively, on a single jack.;

. 56'and under roll 48.

y and the number of sets of rows, namely four,

correspond with lfour of the arms 28 upon the jack. A greater number of erforations than used may' be employed. he number of lates 98 are sufficient to receive through The strands after passlng over the back roll 56 traverse a series of threadplates 102 arranged end to end on the bar and engage the warp bea-m. These plates have rows ofl perforations 103 and 104 corresponding in number and arrangement with t e per orations 99 and 100 respectively. These plates are preferably arranged several deep shown in Fig. 4.` When so arranged a convenient met od of attachment consists of dowel pins 106 in the bar which pass loosely through openings 107 inthe plates. v In an opening 108 in the bar is the shank 109 `of` a clamp .having a finger 110 engaging the rearmost plate. 'A nut 111 on the threadedv opposite endv112 of the shank operates the clamp. The reason for the multiple arangement of the plates 102 is that when the filled warp beam is removed from the machine, the plates 104 in the rearmost row are also removed with the beam and maintain the several strand ends separate.

The operation ofthe machine is as follows: The warp beam'52 is placed in the -frameand engaged by the coupling 73 to the shaft 71 which is rotated by the driving shaft 61'through the described driving connections. The strands 41 having been thread y ed as described and engaged at their ends to the bea-m, are now drawn from the jacks.

-The passage of the strandsl over vthe rollers 56 and under roller 48 imparts the necessary tension to the series. l

In threading the strands through'the rear plates 102 after threadin the front'plates 98 requiresample room. gI'his is secured by elevating the roll 58 temporarily above the horizontal plane of the rolls 56 and plates. The elevation is effected by depressing the pedal 90 which is thereupon engaged by the latch 87, and the beam remains elevated during thethreading operation.

' In'an apparatus of the character described, the combination with the jacks, the .warp frame,`the warp beam, and means for driving the same, of tension rolls on the frame between'thebeam and jacks for supporting 4strands from the jacks, an idler roll resting in the frame. intermediate and below the first rolls, a rock shaft journaled in the frame adjacent the idler roll, arms on the shaft enga ing the ends ofthe idler roll, a third arm ast tothe rody at an angle to the first arms, and means for vibrating the third arm.

In testimony whereof I have affixed my signature.
